Roland Griffiths, the researcher responsible for this assault on common sense, isn’t exactly a reliable source. The director of the U.S. National Institute on Drug Abuse has already rebutted his claim that caffeine is a psychoactive drug. And Griffiths’s earlier caffeine “addiction” study involved just seven human subjects — including himself and a family member.

His latest research also ignores a well-regarded 1999 study that demonstrated that one to three cups of coffee per day has no effect on the region of the brain responsible for addiction.

If the definition of addiction continues to be stretched to its breaking point, it won’t be long before our children need prescription drugs to break their peanut-butter-sandwich habits.
